SASH-HOLDER.

Specification of Letters Patent.

Patented July 21, 1908.

' Applicationfiled July 3, 1907. Serial No. 382,019.

To all whom it may concern:

Be it known that I, WILLIAM MILLER DIGHT, a citizen of the United States, residing at Jackson Center, in the county of Mercer and State of Pennsylvania, have invented certain new and useful Improvements in Sash-Holders, of which the following is a specification, reference being had therein to the accompanying drawing.

My present invention relates to improvements in sash holders, and has for its object a simple, durable and efficient device, adapted to be carried by the sash, and pro vided with means which are thrown into and out of engagement with the window frame, to hold the window sash at any desired adjustment, or allow the window to be moved freely.

The main device is inclosed in a case, and has two clamps or arms, which are normally held in engagement with the window frame by means of a spring, a cam operated by a handle and mounted in the casing, being operated to spread the clamps to release their ends from the window frame. The clamps may be either provided with a roughened engaging surface, or may be pocketed upon their ends to receive a non-slipping substance, such as leather or rubber, or the window frame may have serrations or corrugations to be engaged by the clamps.

' To clearly illustrate my invention, I would refer to the accompanying drawings, in which Figure l is a front elevation of the device in operable position, a portion of the casing being broken away to show the interior mechanism. Fig. 2 is a similar view with the clamp disengaged. Fig. 3 is a section through one of the clamps, showing the nonslipping substance in place.

Referring to the drawings :A designates the window frame and B the sash. Mounted upon the sash is the base plate 1 of the casing 2, which is secured to the sash in any desirable manner. Passing through the casing and base plate is a rivet 3, which also serves as a pivot for the eyed ends 4, of the two arms or clamps 5, whose engaging ends 6, are at angles to the body, as shown, and are provided with receptacles 7 for the block 8, of non-slipping substance, such as rubber or leather. Mounted upon the pivot between the slots 9, of the ends 4, of the arms, and have its terminals 10 projecting through said slots and resting in the channels 11, of each arm, is the spring 12, which normally exerts a tension upon the terminals so as to bring the engaging ends of the arm together, as shown in Fig. 1. By this means, the en gaging ends are always held in engagement with the window frame, and should the frame be provided with serrations or corrugations, the engaging ends are similarly provided and thus firmly lock or hold the sash. As shown, the block 8 engages the frame and holds the sash.

Should it be desired to release the engaging ends of the arms from the frame, the handle 13 is operated and assumes the position shown in Fig. 2, at which point the cam or double-end bar 14, carried within the casing between the terminals of the arms, engages the said arms upon their inner faces and pushes the terminals apart and this action brings the engaging ends within the casing and away from the frame, so that the window sash may be freely moved up or down. When it is desired to release the arms from engagement with the cam, a slight touch upon the handle will move the cam or bar so that it will be at an angle to the terminals, at which point the spring will project the en gaging ends of the arms, engaging the frame, and causing the cam or bar to lie parallel with the terminals.

What I claim as new, is

In combination with a window frame and sash, of a sash holder mounted upon the sash and o posed to the frame, and comprising a base p ate, a casing secured thereto and open toward the frame, a air of arms having slotted inner ends and rame engaging outer ends, a common pivot for securing the slotted ends of the arms within the casing, a spring having a coil mounted on the pivot between the arms and having its terminals entering the slots of the arms to normally hold the free frame engaging ends in engagement with the frame, a bar pivotally mounted within the casing intermediate of the ends of the arms, and a handle for turning the bar to spread the free ends of the arms apart and release the same from the window frame.

In testimony whereof I afliX my signature in presence of two witnesses.

WILLIAM MILLER DIGHT.
